"I can try to make sure that the Milwaukee Police Department and officers receive training necessary so they can be better equipped for crisis intervention," he said.

The mayor said he hopes that any demonstrations will peaceful.

“Today’s decision reminds us we have a lot of work to do in the weeks, months and years ahead to heal and find common ground in community police relations," Barrett said.

Milwaukee Common Council President Michael Murphy asked potential demonstrators to not to put members of the public in harm's way.

"It is everyone’s right to make their voices heard, just as it is everyone’s right to go about their business in safety. My thoughts and prayers go to everyone involved."

Milwaukee Alderman Bob Donovan said he believes Chisholm made the right decision.

"It’s a choice that is based on facts -- not on rhetoric, not on politics, not on protests, but on facts."

Donovan also said the police officers aren't the problem, they are part of the solution.

"These brave men and women put their lives on the line daily. Sadly, they are called upon to man the fine line that prevents our neighborhoods, both nationally and locally, from descending into utter chaos. And yet, many people consistently fail to recognize the sacrifices that our police officers make on a daily basis," he said.

U.S. Rep. Gwen Moore tweeted, "I assure you, our efforts to pursue a fair and equitable outcome for Dontre's family are far from over."

She said she is "deeply disappointed" in the decision.

Milwaukee County Supervisor David Bowen said he questions Chisholm's decision.

"The 14 shots fired seems excessive for an unarmed citizen who was not known to act violently prior to police contact and calls into question the decision not to file criminal charges while calling this justified self-defense," Bowen said. “This is a tragedy that occurs far too frequently both in our community and around the country. We are saddened and outraged, and we want justice from a system that clearly attempts to be the ‘Just Us’ system. It is imperative to our cause for a better future that massive numbers of people engage in creative protest."

NAACP President James Hall Jr. issued a news release stating what it believes needs to be addressed:

-- It supports the right to engage in lawful protest.-- It encourages those who do protest to do so peacefully.-- The NAACP joins the Hamilton family to request a federal investigation to determine whether criminal charges are warranted.-- It supports the family's efforts in any civil actions it may undertake.

Voces de la Frontera, released the following statement Monday afternoon:

“We condemn District Attorney John Chisolm’s decision to not charge fired police officer Christopher Manney with any crime for killing Dontre Hamilton. To ensure positive police-community relations, we must hold law enforcement officials to high standards under stressful situations. There was no need to fire 14 rounds in a lethal manner at a man who represented no danger."
